Medicine isn’t an entirely rational process anywhere in the world, and that’s to its credit. Medicine treats a body, and a body is composed of explicitly non-rational dimensions. Examples of when rationality ran amok: the radical mastectomy and the peak of high-dose chemotherapy. Both of these processes made complete sense in terms of their deductive reason. It was only after an arduous and repetitive cycle of long-term studies that these procedures were disarmed. And it wasn’t a more rational process that stepped in for them.
